Unhappy Electrical problem

When I am hooked up to 120vt everything works however my battery looses it's charge over time. When not hooked up to 120vts the battery system does not work inside the camper. All the outside functions like slide, stabilizers, and awning work. Any one have a clue what might be going on?
Thanks,

Does your battery charger on 30/50 AMP?

No. Actually it discharges. If I leave it hooked up eventually the battery goes dead.

It can be one of two things...the battery is done and won't hold a charge or the camper's converter isn't charging the battery when plugged into shorepower. If you have a voltage tester, the converter should be putting out at least 13.5V at the battery if it's working correctly. A fully charged battery should read around 12.6V when not plugged into shorepower. If the converter checks out, you could take the battery to as auto parts store and have it load tested to be sure.

If you don't have a battery disconnect switch it will eventually discharge in 7-10 days from draw from the CO2 detector, radio clock, etc.

I will check the converter. The battery checks out OK. Would this be the case with the lack of battery power inside the camper? I thought the converter was working since everything works on shorepower.

Something is amiss here.

They only way for all the 12v items to work
A the battery has to be charged.
B the converter charges the battery.

Your battery dies eventually when shore power is hooked up?

Or it dies eventually with shore power disconnected? "It should"

So do you charge the battery with a portable charger?

Yes. If I disconnect the battery it will hold a charge forever.

Then a few things.

1 fuse protection on converter is blown.
2 circuit breaker to battery is tripped or bad.
3 converter is smoked.


If it's a wfco converter there's a trouble shooting guide in the "files" section on upper left hand of frf web page in the green.
Select the file with your model number then trouble shoot away.

If the converter checks out but the battery is losing voltage while on shorepower, I only thing I can think of is a short to ground somewhere on the 12V side.

This sounds like the frame fuse from the battery to the converter is open.

Find the fuse.
Press the tiny button on the side and see if it clicks in.
If so everything should work properly again.

Everything powered by pigtail is working, but power from the battery is not getting to or from the converter.

Thank you everyone. I am back in action! The reset under the camper was the answer. All your suggestions lead me to finding the answer. Thanks again and have a Merry Christmas!
